Create (or extend) .cursor/mcp.json in your project — or
~/.cursor/mcp.json to enable it globally:
{
"mcpServers": {
"seesaw": {
"url": "https://api.seesaw.fun/mcp",
"headers": {
"Authorization": "Bearer sspat_YOUR_KEY"
}
}
}
}
If the config file lives in a repo, keep your real key out of git — use the
global ~/.cursor/mcp.json, or inject the key via your team’s secret
tooling.
Verify
Open Settings → MCP: seesaw should show a green dot and list 14
tools. Then ask the agent:
Search SeeSaw for topics about bitcoin and show the current odds.
Troubleshooting
| Symptom | Likely cause |
|---|
| Red dot / auth error | Key typo or revoked key — check the Authorization value |
| Server missing | JSON syntax error in mcp.json, or Cursor needs a restart |
| Tool errors mentioning retry | Rate limited — see Rate limits |
